Up to 5 effects can be used simultaneously, chained together any way you like. In addition, there are 68 built-in rhythm accompaniment patterns, and you can connect headphones to the output jack (as well as portable music players to the auxiliary input jack) for silent practice sessions. There's an onboard chromatic tuner that supports all standard guitar tunings, including open and drop tunings, and a Looper feature that enables you to record up to 30 seconds of CD-quality audio. Loop length can be set either manually or to a preset number of quarter notes (up to 64 beats), and you can loop to any rhythm pattern, with automatic quantization that ensures seamless start and end times. Programming is simple and straightforward, thanks to a streamlined user interface and the large backlit LCD screen.

Advanced features such as Copy and Swap make it easy to organize your patches for live performance. An Auto Save function ensures that your edits are stored automatically, and a Pre Select feature allows you to scroll through patches silently while keeping the current patch operational. The G1Xon even provides a built-in expression pedal that enables you to control input level, output level, or any selected effect parameter.

Dozens of different waysto make you a guitar hero

Both the G1on and the G1Xon allow you to choose from 100 different onboard DSP effects. (The G1Xon offers 5 additional pedal-controlled effects.) For ease of use, these are organized into the following categories:

Overdrive / Distortion Eighteen of the best boosters, overdrives, fuzzes and lead guitar sounds you've ever heard, including simulations of the BOSS OD-1, MXR Distortion+, Marshall Guv'nor, Fuzz Face, Big Muff and Pro Co Rat. Our ExtremeDS effect offers the most powerful gain of any distortion effect in the world, and there's also a simulator that allows your electric guitar to sound like an acoustic.

Amp Twenty-two of the most realistic models ever created, including simulations of classic tube and solid-state amps from manufacturers like Fender, Marshall, Vox, Hiwatt, Mesa Boogie, Orange, Bogner, Matchless and Diezel. Our amp sounds are so lifelike, you'll swear on a stack of speaker cabinets you're listening to the real thing.

Modulation / Special effects Round out your sound with your choice of twenty-four phasers and flangers, plus chorus, pitch shift, tremolo and vibrato. Included are emulations of the ADA Flanger, Boss CH-1 Super Chorus and TC Electronic Corona Chorus, as well as the Zoom HPS, an intelligent harmonizer that plays along in key, and a ring modulator that adds bell-like tones to your guitar. And when you're ready to go after some truly off-the-wall sounds, try out the endlessly rhythmic Slicer.

Delay / Reverb Twenty delays and natural-sounding reverbs, including rooms, halls, plates, springs, and tape delay simulators, all designed to add depth and spaciousness to your sound, with delay times of up to 4 seconds. You'll even find reverse delays, modulated reverbs and particle reverbs here—everything you need to place your guitar in a realistic space … or a totally unearthly one.

G1on/G1Xon Features

The G1on/G1Xon offers a wealth of features that make it easy to dial in the exact sound you want.

Effects Chaining Complex multi-effects made easy.

Question: When is a guitar effects pedal not just an effects pedal? Answer: When it's a multi-effects pedal.The G1on/G1Xon not only allows you to select and edit any of its onboard effects, it enables you to use up to 5 of them simultaneously, chained together in any order you like. This kind of power and flexibility means that you can create rich, complex effects within the unit itself instead of having to use multiple pedals.

??Stompbox chains typically start with dynamics effects such as compression, before routing the signal to wah, EQ, distortion and/or overdrive effects. Modulation and spatial effects such as chorus, delay and reverb are usually placed at the end of the chain.

However, there are no hard and fast rules on how to chain effects. Exciting new sounds can easily be discovered with a little experimentation and some imaginative effect chaining. The G1on/G1Xon gives you the ability to get creative with your effects chaining.

You can also easily edit chains you’ve previously created. Simple changes in the order of effects can alter sounds dramatically. For example, an EQ set before an amp model can result in a radically different sound than having the EQ set after the amp model. That's because putting the EQ before the amp model serves to not only alter the tonal characteristic of the sound but to act as a signal booster as well. All this can be done internally with the G1on/G1Xon—much easier than physically changing the order of stompboxes.

TunerStayin' in tune.

Guitarists know the importance of playing in tune. But it's not just about getting your instrument in tune; it's about keeping it in tune all night. That's no problem if you're using a G1on/G1Xon, because its built-in Tuner makes the task totally stress-free, even under the pressure of a live gig and the heat of stage lighting.

The G1on/G1Xon Tuner is instantly accessible at all times: All you have to do is step on the two foot pedals simultaneously and the backlit LCD screen immediately shows you whether the note you're playing is sharp, flat, or dead on. You can opt to either bypass the currently selected effect (thus giving you a clean, unaffected sound) when tuning, or to mute the signal altogether, allowing you to tune in silence.

The G1on/G1Xon Tuner is incredibly flexible, too: It can be set to a reference of A=440, or any value between 435 and 445, and can be used chromatically or in a variety of standard guitar tunings—even drop tunings of up to 3 semitones.

RhythmsThe perfect accompaniment.

Rhythm training is an important part of every guitarist's craft. The G1on/G1Xon Rhythm function makes it easy and fun to do. 68 realistic-sounding rhythms are at your fingertips: PCM samples of actual drums playing real-life patterns in a variety of different genres—everything from rock to jazz, from Emo to Motown. Dozens of quarter-note, eighth-note and sixteenth-note rhythms are provided, in 4/4, 6/8 (shuffle) and 3/4 (waltz time); for the adventurous, there's even a 5/4 groove!

The Rhythm function can also be used in conjunction with the Looper function (see below), allowing you to craft complex guitar orchestrations overlaying the pattern of your choice.

Looper Build a complete performance.

Got a great lick that you'd like to expand on, or a distinctive chord progression that you think could serve as the foundation for an exciting improvisation or an inspired solo? Explore your creativity to its fullest with the G1on/G1Xon Looper function, which allows you to layer up to 30 seconds of performance (through the effect or effects of your choice) in high quality audio (16-bit 44.1kHz). Recording time can either be set manually or to a preset number of quarter notes, up to 64 beats, and starting and stopping the Looper (as well as readying it for an overdub or clearing its memory altogether) is as easy as pressing a pedal—no hands required.

The G1on/G1Xon Looper can also be used in conjunction with the Rhythm function, allowing you to play along with the pattern of your choice.

Auto Save Edits saved. All the time.

Finally got that perfect effect crafted, but afraid you'll lose it? It'll never happen when you use the G1on/G1Xon's handy Auto Save function. When switched on, whatever you change will automatically be saved.

Alternatively, if you'd prefer the insurance of a safety net (so that you never accidentally overwrite a patch), simply leave Auto Save off. The G1on/G1Xon will then politely ask you if you want to save your edits whenever you move on to a different patch. Settings can be saved to the currently selected memory area, or to any other area, allowing you to place it where it's most convenient.

The G1on/G1Xon makes naming patches a breeze, too—simply use the parameter knob to dial in the characters you want. Patch names can be up to ten characters long, and each patch can be assigned its own level as well, allowing you to ensure consistent volume even when going from a gentle acoustic sound to heavy metal overdrive.?

Pre SelectChoose the effect you want before the audience hears it.

Normally, you'll want to store your custom G1on/G1Xon patches adjacent to one another so that stepping on the right-hand pedal will scroll through them in the order needed—something that's easily accomplished using the handy Copy and Swap functions. In that circumstance, you'll also want the sound to change immediately, and this is the way the G1on/G1Xon normally operates.

However, if you haven't stored your patches in adjacent memory locations, or if you simply get the urge to experiment and change things up in the middle of a performance, just turn on the G1on/G1Xon Pre Select function. This allows you to scroll through patches silently, with the current sound remaining unchanged as you do so. When you find the patch you want to use next, step on both pedals simultaneously and it will be automatically selected, with the sound changing instantly.

Power functions More power to you.

When it comes to powering your G1on/G1Xon, you've got lots of options. It runs on just 4 AA batteries—either alkaline or rechargeable NiMH—or you can use the optional Zoom AD-16 AC adapter to power it from any standard wall socket.

When running on batteries, the G1on/G1Xon powers up automatically when a jack is inserted into its input connector, and a unique "eco" function can be used to automatically power the unit off if unused for 10 hours.

Battery life (when using alkaline batteries) is more than 20 hours, even during continuous use, and a handy "battery remaining" display shows you how much power is remaining. To extend battery life further still, you can opt to have the backlit LCD display turn off automatically after 15 or 30 seconds after the pedal was last used. ?

The G1Xon expression pedal Express yourself.

The G1Xon adds an expression pedal to the two main pedals, allowing you to alter any selected parameter in real time. You can use it for gain drive or volume (affecting either input or output level), to add wah or filtering, to affect delay time or modulation speed, or a variety of other parameters. In addition, the pedal range can be independently adjusted for every patch—you can even set the minimum value higher than the maximum value for reverse pedaling effects.

There's also a simple calibration procedure which enables you to customize pedal sensitivity. Whether you're a feather-light player or a real lead-foot, the G1Xon can adapt to your particular pedaling style.
